Excludes1 — never code together — inherited from A50-A64

The conditions below can never be reported together with A54.5 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • nonspecific and nongonococcal urethritis (N34.1)
  • Reiter's disease (M02.3-)

Use additional code — inherited from Chapter 1

Report an additional code alongside A54.5 to fully describe the condition. A54.5 is sequenced first.

  • code to identify resistance to antimicrobial drugs (Z16.-)

Excludes2 — not included here — inherited from Chapter 1

The conditions below are not part of A54.5, but a patient may have both at the same time. When documentation supports it, A54.5 and the excluded code may both be reported.

  • carrier or suspected carrier of infectious disease (Z22.-)
  • certain localized infections - see body system-related chapters
  • infectious and parasitic diseases complicating pregnancy, childbirth and the puerperium (O98.-)
  • infectious and parasitic diseases specific to the perinatal period (P35-P39)
  • influenza and other acute respiratory infections (J00-J22)

Excludes2 — not included here — inherited from A50-A64
